What Are the Key Differences Between AIG and Berkshire Hathaway Specialty Insurance Representations and Warranties Insurance?

Capacity and Terms

AIG advertises limits up to $100 million per transaction and a typical retention reference, while Berkshire Hathaway Specialty Insurance’s 2025 overview states portfolio capacity up to $25 million and says premiums and retentions vary with deal size and risk. A deal team should ask what capacity is currently available to its transaction and whether additional layers are needed; neither published amount guarantees a quote. [1] [4]

What the Product Description Establishes

AIG describes protection for financial loss from breaches of sellers’ representations and warranties and lists shared, layered and excess structures. BHSI describes R&W as protection beyond negotiated caps and survival periods and as potentially reducing seller escrow. These summaries frame different transaction benefits, so buyers and sellers should ask each insurer how the negotiated indemnity and policy interact. [1] [4]

  • Ask AIG to name the issuing entity and confirm the proposed retention, limit and structure. [1]
